People still debate whether the earth is flat!The fact people at a variety of levels are debating it, I'd say arguable is a reasonable comment.
I don't disagree with the abuse of Zionist etc, it does the same thing. Neither are productive in resolving the problem.
Seriously - the problem with offender profiling is really obvious. Most people of whatever group you like to choose are not criminals. Therefore any state action that targets any group based on profiling will automatically mean that many innocent people are targeted. This is exactly the wrong way to encourage non-racist behaviour as it is divisive. I wouldn't mind betting that proportionally more GBH offences are committed by males taller than 6ft. But no-one would seriously propose that as a criterion for say a stop and search policy. But blacks are still subject to that sort of thing getting on for 50 years after it was identified as an issue. The only conceivable explanation is racism.
